This music festival is undoubtedly the first of its kind in Singapore, being held on board Royal Caribbean International’s ‘"Voyager of the Seas", one of the world's largest cruise liners. The luxurious vessel itself has some pretty impressive features, such as 14 guest decks, a Vegas-style casino, a FlowRider surf simulator and the first-ever skating rink at sea. There's a pretty wicked line-up as well, with international headliners like Chvrches, The Bloody Beetroots and Lil Jon.
